title: Di-aqua-bis-[2-(2-hy-droxy-eth-yl)pyridine-κ(2) N,O]cobalt(II) dichloride.
abstract: In the title salt, [Co(C7H9NO)2(H2O)2]Cl2, the Co(II) cation, located on an inversion center, is N,O-chelated by two hy-droxy-ethyl-pyridine ligands and coordinated by two water mol-ecules in a distorted O4N2 octa-hedral geometry. In the crystal, the Cl(-) anions link with the complex cations via O-H⋯Cl hydrogen bonds, forming a three-dimensional supra-molecular architecture. π-π stacking is observed between the pyridine rings of adjacent mol-ecules [centroid-centroid distance = 3.5810 (11) Å].
